Abstract

La présente invention se rapporte à un procédé et à un appareil destinés à traiter un signal vidéo, qui permettent d'accroître la précision de la prédiction d'un vecteur de mouvement par l'intermédiaire d'une mise à l'échelle d'un vecteur de mouvement qui prend en compte une différence de distance temporelle entre des images de référence. A cet effet, la présente invention fournit un procédé de traitement de signal vidéo et un appareil de traitement de signal vidéo qui fait appel à celui-ci et le procédé comprend les étapes consistant à : sélectionner au moins un vecteur de mouvement de partition de voisinage pour une prédiction du vecteur de mouvement de la partition courante ; mettre à l'échelle le vecteur de mouvement de partition de voisinage, qui a été sélectionné, lorsque l'image de référence du vecteur de mouvement de partition de voisinage est différente de l'image de référence de la cloison courante ; acquérir une valeur de prédiction de vecteur de mouvement de la partition courante à l'aide du vecteur de mouvement mis à l'échelle ; et acquérir un vecteur de mouvement de la partition courante à l'aide de la valeur de prédiction de vecteur de mouvement.
